[0053] Many specific details are described in the following description to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways than those described herein, and those skilled in the art can make similar generalizations without violating the connotation of the present application, so the present application is not limited by the specific implementation disclosed below.

[0054] At present, the mainstream 3D printing technologies for silicone products are material extrusion molding technology and photopolymerization curing technology. Extrusion molding technology is limited by the curing speed of silicone, resulting in low printing efficiency. Photopolymerization curing technology adds photosensitive polymers to silicone, which trigger cross-linking reactions and promote silicone curing through ultraviolet or infrared irradiation. In addition, the photosensitive polymers in photopolymerization curing technology and a series of subsequent reactions limit product applications and pose safety risks.

[0055] Therefore, the embodiment of the present application provides a laser 3D printing silicone system to solve the problem in the prior art of how to promote silicone curing and improve printing efficiency while ensuring material safety. The present application also relates to a laser 3D printing silicone method.

[0056] The present application is described in detail below through specific embodiments and drawings.

[0057] The present application embodiment provides a laser 3D printing silicone system, as follows Figure 1 The laser 3D printing silicone system is described in detail. Figure 1 It is a schematic framework diagram of a laser 3D printing silicone system provided in an embodiment of the present application.

[0058] In this embodiment, the laser 3D printing silicone system includes a laser printing module 10, a silicone supply module 20 and a data processing module 30; wherein the silicone supply module 20 is used to store and provide corresponding measured silicone materials. The data processing module 30 is used to obtain data information of the object to be printed, generate corresponding printing data according to the data information, and send the printing data to the laser printing module 10. The laser printing module 10 is used as a heat source to receive the printing data, and perform laser 3D printing on the silicone material according to the printing data, and heat and cure the silicone material to form the target object.

[0059] It should be noted that, in this embodiment, the silicone material is a silicone material containing fluoride, and the silicone material also contains component A and component B. The silicone material of this component can be mainly used to manufacture the orthodontic appliance. Of course, in other examples, the silicone material can only contain silicone components.

[0060] Specifically, in the present embodiment, the silicone supply module 20 includes a silicone containing tank, a silicone storage device and a control device, and the control device includes a microprocessor. The silicone containing tank is used to contain silicone, and the silicone containing tank is provided with a substrate, and the substrate allows the laser to pass through and then perform laser printing on the silicone material. The silicone storage device is used to store silicone and provide silicone to the silicone containing tank. The silicone containing tank and the silicone storage device are connected via a delivery pipeline. The microprocessor is connected to the data processing module 30 for communication, and is used to obtain the printing data of the data processing module 30, and control the silicone storage device to deliver the corresponding metered silicone according to the printing data. A flow meter is provided in the silicone storage device for controlling the flow of silicone. Thus, waste of silicone material can be avoided.

[0061] In this embodiment, the data processing module 30 is used to obtain data information of the object to be printed, generate corresponding printing data according to the data information, and send the printing data to the laser printing module 10. In one example, the object to be printed includes at least an orthodontic appliance.

[0062] The data processing module 30 is used to obtain data information of the object to be printed and generate corresponding printing data according to the data information, including the following steps:

[0063] Step S101: Analyze and model the data information of the object to be printed to obtain 3D shape data of the object to be printed.

[0064] In this step, the object to be printed includes a silicone object to be printed, that is, the object is made of silicone material. Each object to be printed has its own morphological structure. In this regard, the data information of the object to be printed can be analyzed to obtain morphological feature data corresponding to the object to be printed. Morphological feature data refers to the shape structure of the object to be printed and the corresponding coordinate position of each shape structure in three-dimensional space. The morphological feature data can fully reflect the three-dimensional morphological structure of the object to be printed. Specifically, in one example, the data information of the object to be printed includes image data of the object to be printed, and the image data of the object to be printed can be subjected to image recognition analysis to obtain morphological feature data corresponding to the object to be printed. In another example, the object to be printed can be directly physically scanned to obtain scan data, and the scan data has a one-to-one correspondence with the physical data of the object to be printed, and then the obtained scan data can be converted into morphological feature data of the object to be printed.

[0065] Then, the morphological feature data is processed by data model to obtain standard model data associated with the object to be printed. In this step, the data model processing of the morphological feature data mainly adopts a linear normalization processing method so that the morphological feature data can reach the standard model data that can be processed by the preset model.

[0066] Finally, a preset model is obtained, and the standard model data is input into the preset model to obtain 3D morphological data for the object to be printed. Specifically, in this step, the preset model is obtained by pre-training, that is, the standard model data of the above-mentioned morphological feature data is obtained, and the standard model data is used as a sample for training, which can be called a standard model data sample. An initial model is constructed, the parameters of the initial model are set, and the standard model data sample is input into the initial model. The initial model is iteratively trained with a large number of standard model data samples, and the output result of the initial model is compared with the preset standard 3D morphological data. If the comparison result is consistent, the initial model is determined as the preset model; if the comparison result is inconsistent, the standard model data sample is continuously input into the initial model for iterative training until the output result is consistent with the preset standard 3D morphological data. Then, after obtaining the preset model, the standard model data is input into the preset model to obtain the 3D morphological data for the object to be printed.

[0067] Step S102: obtaining slice information of several layers of 3D morphological data of the object to be printed.

[0068] After obtaining the 3D morphological data for the object to be printed, obtain the slice information of several layers of the 3D morphological data for the object to be printed. Specifically, first, determine the division dimension direction of the 3D morphological data of the object to be printed. Among them, the division dimension direction of the 3D morphological data of the object to be printed can be any direction of the 3D morphology of the object to be printed in the spatial coordinate system. The division dimension direction of this embodiment refers to the bottom-up direction of the 3D morphology of the object to be printed in the spatial coordinate system. Then, in the division dimension direction, the 3D morphological data of the object to be printed is divided into several layers of slices. Specifically, the total length data of the 3D morphology of the object to be printed in the 3D morphological data of the object to be printed in the division dimension direction is obtained, and the 3D morphology of the object to be printed is divided into several layers of slices according to the total length data of the 3D morphology of the object to be printed. Each layer of slices can be of equal thickness or unequal thickness. The specific thickness of the slices can be divided according to the requirements of laser printing. Then, the contour morphological information of each layer of the slices and the spatial coordinate information of the contour morphology of the slices in the spatial coordinate system are obtained. Based on the fact that the 3D shape data of the object to be printed includes the 3D shape of the object to be printed, after the 3D shape of the object to be printed is divided into several layers of slices, each layer of the slices has corresponding contour shape and space coordinate information.

[0069] Furthermore, in the spatial coordinate system, the slices of each layer not only have corresponding contour morphology and spatial coordinate information, but also the slices of each layer can be imaged, that is, the slices of each layer are identified to form a slice image, and each pixel point in the slice image has a corresponding spatial sub-coordinate, and each pixel point in the slice image has a corresponding spatial sub-coordinate that can constitute the spatial coordinate information of the slices of each layer.

[0070] Step S103: Generate corresponding printing data according to the slice information of several layers.

[0071] After obtaining the slice information of several layers, the corresponding printing data is generated according to the slice information of several layers. Specifically, since there are many layers of slices, in order to clarify each layer, the slices of each layer are encoded to form coded slices with coding information. For example, the coded slice of the first layer is coded slice 1, the coded slice of the first layer is coded slice 2, the coded slice of the first layer is coded slice 3... and so on. Then, according to the coding information of the coded slices, printing slices that can be stacked in sequence are constructed, and printing slices refer to slices that can be used for printing. In this embodiment, the object to be printed is generally a three-dimensional object, such as an orthodontic appliance. When printing the three-dimensional object to be printed, the corresponding slices need to be printed in a specified printing order, and then when determining the printing data, the coded slices with coding information are given the printing order of the slices, but it is necessary to further stack all the slices in sequence to form a complete three-dimensional object. Therefore, this step needs to construct printing slices that can be stacked in sequence according to the coding information of the coded slices.

[0072] Then, the contour morphology of each of the printed slices and the spatial coordinate information corresponding to the contour morphology are obtained, and the empty print information between adjacent printed slices is determined according to the contour morphology of the printed slices and the spatial coordinate information corresponding to the contour morphology, wherein the empty print information refers to the information of stopping printing between adjacent printed slices. Among them, stopping printing may involve the situation of replacing the print head, that is, replacing a laser with a different laser scale to print the next slice. Alternatively, stopping printing may involve the situation that the printing temperature is too high and the printing needs to be stopped to cool down, etc., in order to ensure the printing accuracy during the printing process. Alternatively, stopping printing requires adjusting the corresponding working power of the laser, etc. In the present embodiment, the empty print information between adjacent printed slices is determined according to the contour morphology of the printed slices and the spatial coordinate information corresponding to the contour morphology, that is, the contours of printed slices of different morphological thicknesses need to be printed by lasers of different scales. Specifically, determining the empty print information between adjacent print slices according to the contour morphology of the print slices and the spatial coordinate information corresponding to the contour morphology includes respectively obtaining thickness information in the contour morphology of adjacent print slices, and comparing the thickness information in the contour morphology of adjacent print slices with preset standard thickness information respectively; if the thickness information of the next layer of print slices is different from the preset standard thickness information, then generating corresponding empty print information.

[0073] Finally, corresponding printing data is generated according to the outline shape of the printed slice, the space coordinate information corresponding to the outline shape, and the blank printing information.

[0074] Furthermore, in this embodiment, the object to be printed includes a silicone object to be printed, and the silicone object to be printed includes at least an orthodontic appliance. In this regard, the data processing module 30 is used to obtain data information of the object to be printed and generate corresponding printing data according to the data information, which may include the following steps:

[0075] Step S201: Obtaining oral cavity parameters.

[0076] Specifically, in this step, the oral parameters at least include: tooth morphology parameters, occlusal relationship parameters, molar relationship parameters and oral soft tissue parameters. The oral parameters are obtained by: obtaining through an intraoral scanner or a patient's tooth impression; or obtaining through an intraoral scanner or a jaw frame; or obtaining through optical scanning technology, X-ray imaging technology, ultrasonic imaging technology, computer tomography CT scanning or magnetic resonance imaging technology.

[0077] Step S202: performing 3D modeling according to the oral cavity parameters to obtain 3D morphological data for the object to be printed.

[0078] After obtaining the oral parameters, 3D modeling is performed according to the oral parameters to obtain 3D morphological data for the object to be printed. Specifically, first, the length information and width information of the upper and lower dentition, the morphological information of the labial and buccal contours and the lingual contours of the upper and lower dentition, and the gingival position information of each tooth in the upper and lower dentition are obtained according to the oral parameters. In one example, the width information of each upper and lower dentition can be calculated and fitted by the incisor width, the intercanine width and the intermolar width. While obtaining the incisor width, the intercanine width and the intermolar width, the incisor, canine and molar can be obtained as position information respectively, so as to obtain the length information of the upper and lower dentition according to the incisor width, the intercanine width and the intermolar width and the corresponding position information respectively. Then, the spacing of the occlusal surfaces between the upper and lower dentitions is obtained according to the length information and width information of the upper and lower dentitions, wherein the spacing of the occlusal surfaces can clearly determine the degree of opening of the upper and lower jaws. In one example, the shapes of the labial and buccal contours and the lingual contours of the upper and lower dentitions, as well as the gingival positions of each tooth in the upper and lower dentitions are obtained based on oral parameters. Then, the shapes of the labial and buccal contours and the lingual contours, and the gingival positions of each tooth are connected and smoothed to determine the standard shape after processing. For example, according to the smoothed gingival position connecting line between two teeth in different dentition areas (such as incisors, canines, molars, etc.), the outer wall length of the digital model of the orthodontic appliance is fitted and adjusted. The outer wall length can satisfy that the orthodontic appliance does not compress the gums, such as the outer wall length of the orthodontic appliance does not reach the gingival position.

[0079] Then, data model processing is performed based on the length information and width information of the upper and lower dentition, the morphological information of the labial and buccal contours and the lingual contours of the upper and lower dentition, and the gingival position information of each tooth in the upper and lower dentition to obtain standard model data associated with the object to be printed. In this step, the data model processing of each data information mainly adopts a linear normalization processing method so that the above-mentioned each data information can reach the standard model data that can be processed by the preset model.

[0080] Finally, a preset model is obtained, and the standard model data is input into the preset model to obtain 3D morphological data for the object to be printed. Specifically, in this step, the preset model is obtained through pre-training, that is, the standard model data of the above-mentioned various data are obtained, and the standard model data is used as a sample for training, which can be called a standard model data sample. An initial model is constructed, the parameters of the initial model are set, and the standard model data sample is input into the initial model. The initial model is iteratively trained with a large number of standard model data samples, and the output result of the initial model is compared with the preset standard 3D morphological data. If the comparison result is consistent, the initial model is determined as the preset model; if the comparison result is inconsistent, the standard model data sample is continuously input into the initial model for iterative training until the output result is consistent with the preset standard 3D morphological data. Then, after obtaining the preset model, the standard model data is input into the preset model to obtain the 3D morphological data for the object to be printed.

[0081] Step S203: Acquire slice information of several layers of 3D morphological data of the object to be printed.

[0082] After obtaining the 3D morphological data for the object to be printed, obtain the slice information of several layers of the 3D morphological data for the object to be printed. Specifically, first, determine the division dimension direction of the 3D morphological data of the object to be printed. Among them, the division dimension direction of the 3D morphological data of the object to be printed can be any direction of the 3D morphology of the object to be printed in the spatial coordinate system. The division dimension direction of this embodiment refers to the bottom-up direction of the 3D morphology of the object to be printed in the spatial coordinate system. Then, in the division dimension direction, the 3D morphological data of the object to be printed is divided into several layers of slices. Specifically, the total length data of the 3D morphology of the object to be printed in the 3D morphological data of the object to be printed in the division dimension direction is obtained, and the 3D morphology of the object to be printed is divided into several layers of slices according to the total length data of the 3D morphology of the object to be printed. Each layer of slices can be of equal thickness or unequal thickness. The specific thickness of the slices can be divided according to the requirements of laser printing. Then, the contour morphological information of each layer of the slices and the spatial coordinate information of the contour morphology of the slices in the spatial coordinate system are obtained. Based on the fact that the 3D shape data of the object to be printed includes the 3D shape of the object to be printed, after the 3D shape of the object to be printed is divided into several layers of slices, each layer of the slices has corresponding contour shape and space coordinate information.

[0083] Furthermore, in the spatial coordinate system, the slices of each layer not only have corresponding contour morphology and spatial coordinate information, but also the slices of each layer can be imaged, that is, the slices of each layer are identified to form a slice image, and each pixel point in the slice image has a corresponding spatial sub-coordinate, and each pixel point in the slice image has a corresponding spatial sub-coordinate that can constitute the spatial coordinate information of the slices of each layer.

[0084] Step S204: Generate corresponding printing data according to the slice information of several layers.

[0085] After obtaining the slice information of several layers, the corresponding printing data is generated according to the slice information of several layers. Specifically, since there are many layers of slices, in order to clarify each layer, the slices of each layer are encoded to form coded slices with coding information. For example, the coded slice of the first layer is coded slice 1, the coded slice of the first layer is coded slice 2, the coded slice of the first layer is coded slice 3... and so on. Then, according to the coding information of the coded slices, printing slices that can be stacked in sequence are constructed, and printing slices refer to slices that can be used for printing. In this embodiment, the object to be printed is generally a three-dimensional object, such as an orthodontic appliance. When printing the three-dimensional object to be printed, the corresponding slices need to be printed in a specified printing order, and then when determining the printing data, the coded slices with coding information are given the printing order of the slices, but it is necessary to further stack all the slices in sequence to form a complete three-dimensional object. Therefore, this step needs to construct printing slices that can be stacked in sequence according to the coding information of the coded slices.

[0086] Then, the contour morphology of each of the printed slices and the spatial coordinate information corresponding to the contour morphology are obtained, and the empty print information between adjacent printed slices is determined according to the contour morphology of the printed slices and the spatial coordinate information corresponding to the contour morphology, wherein the empty print information refers to the information of stopping printing between adjacent printed slices. Among them, stopping printing may involve the situation of replacing the print head, that is, replacing a laser with a different laser scale to print the next slice. Alternatively, stopping printing may involve the situation that the printing temperature is too high and the printing needs to be stopped to cool down, etc., in order to ensure the printing accuracy during the printing process. Alternatively, stopping printing requires adjusting the corresponding working power of the laser, etc. In the present embodiment, the empty print information between adjacent printed slices is determined according to the contour morphology of the printed slices and the spatial coordinate information corresponding to the contour morphology, that is, the contours of printed slices of different morphological thicknesses need to be printed by lasers of different scales. Specifically, determining the empty print information between adjacent print slices according to the contour morphology of the print slices and the spatial coordinate information corresponding to the contour morphology includes respectively obtaining thickness information in the contour morphology of adjacent print slices, and comparing the thickness information in the contour morphology of adjacent print slices with preset standard thickness information respectively; if the thickness information of the next layer of print slices is different from the preset standard thickness information, then generating corresponding empty print information.

[0087] Finally, corresponding printing data is generated according to the outline shape of the printed slice, the space coordinate information corresponding to the outline shape, and the blank printing information.

[0088] After obtaining the printing data, the data processing module 30 sends the printing data to the laser printing module 10. In one example, the laser printing module 10 serves as a heat source. The laser printing module 10 includes at least one laser and at least one driving mechanism. The laser is connected to the driving mechanism so that the laser is driven by the driving mechanism to move to a specified position to print the silicone material. The laser printing module 10 receives the printing data, and performs laser 3D printing on the silicone material according to the printing data, and heats and cures the silicone material to form a target object. It should be noted that when the laser printing module 10 of this embodiment heats and cures the silicone material in the silicone pool, it prints from the bottom to the top, that is, the laser in the laser printing module 10 emits laser to irradiate the silicone pool from the bottom to the top, so as to heat and cure the silicone material in the silicone pool layer by layer.

[0089] Specifically, first, determine the base point printing position for the silicone material. When printing the silicone material, it is necessary to determine the base point printing position for the silicone material, and the base point printing position is the reference point for printing the silicone material. Then, construct a printing trajectory for the silicone material according to the base point printing position and the printing data. Specifically, first, construct 3D model data of the object to be printed in the silicone material according to the base point printing position. When laser printing is performed on the silicone material, it is necessary to outline the 3D model data of the object to be printed in the silicone material. After outlining the 3D model data of the object to be printed in the silicone material, obtain the entity printing slice for the silicone material according to the printing data and the 3D model data. The entity printing slice of the silicone material refers to the slice actually printed by the laser. The printing data includes the contour morphology of the printed slice and the spatial coordinate information corresponding to the contour morphology, as well as the blank printing information between the printed slices. Then, it can be determined that the entity printing slice of the silicone material includes the contour morphology of the entity printing slice and the spatial coordinate information corresponding to the contour morphology, so that the printing trajectory for the silicone material can be constructed according to the printing data and the entity printing slice. Finally, the silicone material is laser 3D printed according to the printing track, and the silicone material is heated and cured to form a target object.

[0090] In this embodiment, in order to improve the printing speed, each of the print slices can be divided into different print partitions, and the morphological information of each print partition and the spatial sub-coordinates corresponding to the morphology of the print partition, as well as the splicing band information between each of the print partitions, are obtained. Among them, the splicing bands between the print partitions are used to splice adjacent print partitions. Specifically, when the print slices are divided into different print partitions, each print partition can be printed by a corresponding laser, and each print partition has corresponding morphological information and spatial sub-coordinates corresponding to the morphology of the print partition. The corresponding laser can print the print partition according to the morphological information of the print partition and the spatial sub-coordinates corresponding to the morphology of the print partition. As for the splicing bands between adjacent print partitions, in order to improve printing efficiency and printing accuracy, there is an association between the splicing bands between the adjacent print partitions, that is, the morphology of the splicing bands between adjacent print partitions can be spliced, and the spatial coordinate positions of the splicing bands can be docked. The laser can print the corresponding splicing band according to the specific splicing band information to achieve the splicing of adjacent print partitions.

[0091] In this embodiment, an environmental monitoring module 40 is also included, and the environmental monitoring module 40 is used to collect the material temperature information of the silicone material in the printing state, and feed the material temperature information back to the data processing module 30. Correspondingly, the data processing module 30 is also used to obtain the material temperature information and generate corresponding printing data according to the material temperature information. Specifically, since the laser of the laser can generate high energy, it makes the corresponding slice layer also have a very high heat temperature during printing, so as to quickly solidify the silicone, and since the distance between adjacent slice layers is close, a certain amount of heat will affect the printing of the next slice layer. For this reason, it is necessary to monitor the current material temperature information of the current printing slice layer and the temperature information of the silicone material when printing the next printing slice layer at all times during laser printing, so that the print head can adjust to the corresponding printing temperature when printing the next printing slice layer. That is, the current material temperature information of the current printing slice layer of the silicone material and the temperature information of the silicone material when printing the next printing slice layer are obtained, and the printing power information and preheating temperature information for the print head are obtained according to the current material temperature information and the temperature information of the silicone material when printing the next printing slice layer. Finally, corresponding printing data is generated according to the printing power information and preheating temperature information of the print head.

[0092] In this embodiment, an environmental monitoring module 40 is also included. The environmental monitoring module 40 is used to collect the material temperature information of the silicone material and the temperature information of the print head of the laser printing module 10 during the printing state, and feed the material temperature information and the temperature information of the print head back to the data processing module 30. Correspondingly, the data processing module 30 is also used to obtain the material temperature information and the temperature information of the print head, and generate corresponding printing data according to the material temperature information and the temperature information of the print head. Specifically, the current material temperature information of the current printing slice layer of the silicone material and the current temperature information of the print head of the laser printing module 10 when printing the current printing slice layer are obtained. Since the laser of the laser can generate high energy, it makes the corresponding slice layer also have a high heat temperature during printing, so as to quickly solidify the silicone, and since the distance between adjacent slice layers is close, a certain amount of heat will affect the printing of the next slice layer. For this reason, it is necessary to monitor the current material temperature information of the current printing slice layer and the current temperature information of the print head of the laser printing module 10 when printing the current printing slice layer at all times during laser printing, so that the print head can adjust to the corresponding printing temperature when printing the next printing slice layer. That is, the printing power information and preheating temperature information for the print head are obtained according to the current material temperature information and the current temperature information of the print head. Finally, the corresponding printing data is generated according to the printing power information and preheating temperature information of the print head.

[0093] The embodiment of the present application provides a laser 3D printing silicone system, comprising: a laser printing module 10, a silicone supply module 20 and a data processing module 30; wherein the silicone supply module 20 is used to store and provide corresponding measured silicone materials; the data processing module 30 is used to obtain data information of an object to be printed, and generate corresponding printing data according to the data information, and send the printing data to the laser printing module 10; the object to be printed includes at least an orthodontic appliance. The laser printing module 10 is used as a heat source to receive the printing data, and perform laser 3D printing on the silicone material according to the printing data, and heat and cure the silicone material to form a target object.

[0094] The embodiment of the present application provides a corresponding amount of silicone material through the silicone supply module 20, so that the silicone material can meet the printing requirements while avoiding silicone waste. The data processing module 30 generates corresponding printing data according to the data information of the object to be printed, and sends the printing data to the laser printing module 10. The laser printing module 10 acts as a heat source and uses the printing data to perform laser 3D printing on the silicone material, so that the silicone material is heated and cured to form a target object. The laser source of the laser printing module 10 improves the curing, and dynamically optimizes and adjusts the light source and the material extrusion amount to improve accuracy and efficiency. The laser acts as an energy source to promote the curing of silicone without destroying the safety of silicone.

[0095] An embodiment of the present application also provides a laser 3D printing silicone method, which is applied to the laser 3D printing silicone system described above, wherein the laser printing module in the laser 3D printing silicone system serves as a heat source. Figure 4 1 is a schematic flow chart of a laser 3D printing silicone method provided in an embodiment of the present application. The method comprises the following steps:

[0096] Step S301: providing silica gel material in a silica gel pool in a silica gel supply module.

[0097] Specifically, in the present embodiment, the silicone supply module includes a silicone containing tank, a silicone storage device and a control device, and the control device includes a microprocessor. The silicone containing tank is used to contain silicone, and the silicone containing tank is provided with a substrate, and the substrate allows the laser to pass through and then perform laser printing on the silicone material. The silicone storage device is used to store silicone and provide silicone to the silicone containing tank. The silicone containing tank and the silicone storage device are connected via a delivery pipeline. The microprocessor is connected to the data processing module for communication, and is used to obtain the printing data of the data processing module, and control the silicone storage device to deliver the corresponding metered silicone according to the printing data. A flow meter is provided in the silicone storage device for controlling the flow of silicone. Thus, waste of silicone material can be avoided.

[0098] In this embodiment, the silicone material is a silicone material containing fluoride, and the silicone material also contains component A and component B. The silicone material of this component is mainly used to manufacture the orthodontic appliance. Of course, in other examples, the silicone material may only contain silicone components.

[0099] Step S302: Acquire data information of the object to be printed, and generate corresponding printing data according to the data information.

[0100] In this step, the object to be printed includes at least an appliance. The specific content of this step can be found in the description of the above embodiment, and will not be repeated here.

[0101] Step S303: performing laser 3D printing on the silicone material according to the printing data, and heating and curing the silicone material to form a target object.

[0102] The laser printing module performs laser 3D printing on the silicone material according to the printing data. In one example, the laser printing module includes at least one laser and at least one driving mechanism, and the laser is connected to the driving mechanism so that the laser is driven to move to a specified position under the drive of the driving mechanism to print on the silicone material. The laser printing module receives the printing data, and performs laser 3D printing on the silicone material according to the printing data, and heats and cures the silicone material to form a target object.

[0103] Specifically, first, determine the base point printing position for the silicone material. When printing the silicone material, it is necessary to determine the base point printing position for the silicone material, and the base point printing position is the reference point for printing the silicone material. Then, construct a printing trajectory for the silicone material according to the base point printing position and the printing data. Specifically, first, construct 3D model data of the object to be printed in the silicone material according to the base point printing position. When laser printing is performed on the silicone material, it is necessary to outline the 3D model data of the object to be printed in the silicone material. After outlining the 3D model data of the object to be printed in the silicone material, obtain the entity printing slice for the silicone material according to the printing data and the 3D model data. The entity printing slice of the silicone material refers to the slice actually printed by the laser. The printing data includes the contour morphology of the printed slice and the spatial coordinate information corresponding to the contour morphology, as well as the blank printing information between the printed slices. Then, it can be determined that the entity printing slice of the silicone material includes the contour morphology of the entity printing slice and the spatial coordinate information corresponding to the contour morphology, so that the printing trajectory for the silicone material can be constructed according to the printing data and the entity printing slice. Finally, the silicone material is laser 3D printed according to the printing track, and the silicone material is heated and cured to form a target object.

[0104] In this embodiment, in order to improve the printing speed, each of the print slices can be divided into different print partitions, and the morphological information of each print partition and the spatial sub-coordinates corresponding to the morphology of the print partition, as well as the splicing band information between each of the print partitions, are obtained. Among them, the splicing bands between the print partitions are used to splice adjacent print partitions. Specifically, when the print slices are divided into different print partitions, each print partition can be printed by a corresponding laser, and each print partition has corresponding morphological information and spatial sub-coordinates corresponding to the morphology of the print partition. The corresponding laser can print the print partition according to the morphological information of the print partition and the spatial sub-coordinates corresponding to the morphology of the print partition. As for the splicing bands between adjacent print partitions, in order to improve printing efficiency and printing accuracy, there is an association between the splicing bands between the adjacent print partitions, that is, the morphology of the splicing bands between adjacent print partitions can be spliced, and the spatial coordinate positions of the splicing bands can be docked. The laser can print the corresponding splicing band according to the specific splicing band information to achieve the splicing of adjacent print partitions.

[0105] In this embodiment, the method further includes collecting material temperature information of the silicone material and temperature information of the print head of the laser printing module during the printing state, and feeding back the material temperature information and temperature information of the print head to the data processing module. Correspondingly, the data processing module is also used to obtain material temperature information and temperature information of the print head, and generate corresponding printing data according to the material temperature information and temperature information of the print head. Specifically, the current material temperature information of the current printing slice layer of the silicone material and the previous temperature information of the print head of the laser printing module when printing the previous printing slice layer are obtained. Since the laser of the laser can generate high energy, it makes the corresponding slice layer also have a very high heat temperature during printing, and since the distance between adjacent slice layers is close, a certain amount of heat will affect the printing of the next slice layer. For this reason, it is necessary to monitor the current material temperature information of the current printing slice layer and the previous temperature information of the print head of the laser printing module when printing the previous printing slice layer at all times during laser printing, so that the print head can adjust to the corresponding printing temperature when printing the next printing slice layer. That is, the printing power information and preheating temperature information for the print head are obtained according to the current material temperature information and the previous temperature information of the print head. Finally, corresponding printing data is generated according to the printing power information and preheating temperature information of the print head.
